Searching would be great, especially for runes with two effects. But it that’s a bit more tricky to implement at least let us sort them by name. That really can’t be hard to implement, seeing that the sort button is already there.

Just a minor suggestion: could you change the runes menu to group similar runes together? Stacking would be best, but even the option to sort alphabetically would help and must surely be simple to implement. I tend to salvage runes I’ve got loads of (as well as ones I don’t want at all), but at the moment finding them in the menu is like launching some joyless memory puzzle mini-game.
